Z SHEETS-SHEIJT 2 iar and surrounds the usual sleeve lution, or might even rotate several times be-' fore the detent arm 18 again drops into the next following notch. lQhe means whereby this can be accomplished are, of course, obvious to those skilled in the art.

In order to provide means for sounding an alarm at any predetermined time, we mount upon the shaft 7 an alarm record 25 with which a styluson the sound box 26 engages. This sound box is mounted on a tubular arm 27 which is also looselyponnected and communicates with the horn 23. The'cylinder 25 is loosely mounted on the shaft l and is held in place thereon by a collar 25% In order to actuate the record 9-5 at any predetermined time, we connect the disk with a spring actuated alarm shaft which at a predetermined time is released and permitted to rotate. To this end we provide a shaft 28 mounted in the clock casing and driven by an alarm spring, this shaft carrying upon it a pulley 30 over which a belt 29 passes to a pulley 29 which is attached to the disk 25 to rotate therewith.

While we may actuate the record 25 by any of the various alarm sounding and motor mechanisms which are used in clocks, we have shown the shaft 28 as forming the barrel on which is mounted a spring 31, one end of the spring heing' fast to rods 32 projecting from a fixed base 33. Carried on the shaft 28 is a gear wheel 34; which carries upon it pawl 35 which engages with a ratchet wheel 36 on the shaft 28, so that after the spring has been wound by rotating the shaft 28, the unwinding of the spring will act to rotate the gear wheel. lhis gear wheel 34 engages with a pinion 37 on a shaft 38 which carries upon it an escapement wheel 39 of any usual type engaged by an escapement 40, This escapement is mounted on the extremity of a resilient arm ll which extends out at an angle to an arm 42 which. extends outward beyond the face plate 43 which is mounted on the forward. extremitiesof the rods 32.

ll Connected to the outer extremity of the hrm 42 is the connecting rod 44% which at its upper ends is pivotally connected to a pivoted arm 45 which is supported in a raised position by means of an arcuate cam 4:6 mounted on a shaft 4L7. This shaft is tubuupon h the hour hand 6 is mounted. It is,

re: independently rotatable and carriesupon itsouter end the rotatable dial :8. By rotating this dial the sleeve will be 100-- tated which will rotate the cam lG to any desired position so that at any predetermined time the arm 45 will be released, permitting the rod M to drop which will release the arm 42 and this will release one end of the escapement l0, permitting the escapement wheel to rotate, the escapement, however, intermittently engaging said wheel in a manner well known, and thus checking any too speedy rotation of the shaft 28. It is to be understood that while we have shown one means for releasing the shaft 28 and permitting its rotation under the force of the spring 81, we do not wish to be limited to this as there are largenumbers of other forms of alarm releasing mechanism which might be used for this purpose. When the shaft 28 is released, it will rotate and this will give a rotation to the record 25. An

appropriate record is used upon this cylin-,

der and as this is rotated an alarm call will be sounded through the horn This call will continue to be sounded until such time I as the spring 31 runs down.

It will be obvious that many different records might be used for the purpose of calling out or indicating the hours of the day and night, as also for calling out or indicating an alarm signal. Tunes might be played, popular airs reproduced or phrases reproduced for this purpose, and thus a large variety of diiferent sounds be used for indicating the hours in di'llerent clocks.

It will be understood that while we have shown a cylinder record in which the record is placed upon the circumference of the cylinder, we do not wish to be limited to this as it is obvious that a disk record might be used, or indeed a record of any other desired form.

Having thus described the invention, what is claimed as new is:

1. lhe combination. with a clock mechanism, of a shaft, a phonographic record fixedly mounted upon said shaft, :1 phonograiahic record loosely mounted on a shaft, sai records being disposed parallel to each other, a horn, a plurality of tubular arms extending from the horn, a sound box and stylus mounted on each tubular arm, each stylus engaging one of the phonographic records, means operated by the clock mechanism for actuating the record carrying shaft at predetermined intervals throughout the day, an alarm record motor, a connection therefrom. to the loose record on the shaft, means for holding" the motor from actuation, means actuated by the clock for releasing the motor shaft and permitting the sound alarm record to rotate.

The combination with a clock mechanism, of a shaft adapted to be actuated on said shaft for independent rotation, a

horn, tubular arms connected to said horn, a sound box and stylus mounted on each arm and engaging said records, means operated by the clock mechanism for actuating the record carrying shaft at predetermined intervals throughout the day, an independent motor for the alarm record, a connection between said motor and the record to rotate the latter from the former, means for holding the alarm record motor from rotation, and means actuated by the clock mechanism for releasin said alarm record motor and permittin 1t to rotate the alarm sounding record in ependently of the shaft. 1

3. The combination with a clock mecha nism, of a shaft adapted to be actuated thereby, fast and loose phonographic records mounted on the shaft, the loose record bein independently driven and forming an alarm record, a horn, tubular arms extending from said born, a sound box and stylus mounted on each one of the arms, each stylusengaging with one of said records, means operated by the clock mechanism for actuating the hour soundin record at predetermined-1ntervals throu out the day, an alarm record motor, a shat extending therefrom, a belt connectin said. shaft with the loose record for rotating the latter from the former, means for holding the record sup ortiug shaft and the motor. actuatin sha t from rotation and means actuated by the clock mechanism for releasing the record supporting shaft at predetermined intervals and permitting it to rotate and sound an alarm,

and means adapted to be set for an predetermined time and actuated by sai clock mechanism for releasing the motor shaft and permitting it to rotate and operate thealarm sounding record.
